The base 3.6-liter Pentastar V-6, by the way, is impressive as well, and some of High Gear Media's editors prefer it.
Mileage: really not bad
You might not actually see much better mileage with the V-6 though; we averaged nearly 19 mpg over 230 miles of driving—split about equally between Interstates, two-lane back roads, and congested city streets. That's an impressive figure—as good if not better than we'd see in some V-6 crossovers, and likely because the V-8 is geared tall and thrums along below 2,000 rpm most of the time. The V-8's MDS system, which deactivates some of the cylinders when cruising or coasting, surely has a role, too.
Oh, and we even got some brief time off-roading in the Grand. With the Jeep's new Land Rover-like SelecTerrain system, the Grand Cherokee's combination of mechanical and electronic strategies, plus its surprisingly versatile suspension, has the makings of a solid off-roader, too.
With the 2011 Grand Cherokee, Jeep at last has a very nice driving, well-rounded vehicle that does it all and doesn't have any glaring deficiencies 95 percent of the time. Driving on-road is now very grand as well.
